Overview of this book

JMeter is a Java application designed to load and test performance for web application. JMeter extends to improve the functioning of various other static and dynamic resources. This book is a great starting point to learn about JMeter. It covers the new features introduced with JMeter 3 and enables you to dive deep into the new techniques needed for measuring your website performance. The book starts with the basics of performance testing and guides you through recording your first test scenario, before diving deeper into JMeter. You will also learn how to configure JMeter and browsers to help record test plans. Moving on, you will learn how to capture form submission in JMeter, dive into managing sessions with JMeter and see how to leverage some of the components provided by JMeter to handle web application HTTP sessions. You will also learn how JMeter can help monitor tests in real-time. Further, you will go in depth into distributed testing and see how to leverage the capabilities of JMeter to accomplish this. You will get acquainted with some tips and best practices with regard to performance testing.

The aftermath


It was a long night at the Baysoft Training Inc. corporate office. How did this happen? Could this have been avoided? Why were the application and system not able to handle the load? Why weren't adequate performance and stress tests conducted on the system and application? Was it an application problem, a system resource issue, or a combination of both? All these were questions that the management demanded answers to from the group of engineers, which comprised software developers, network and system engineers, Quality Assurance (QA) testers, and database administrators gathered in the meeting room. There sure was a lot of finger-pointing and blame going around the room. After a little brainstorming, it wasn't long before the group had to decide what needed to be done. The application and its system resources needed to undergo extensive and rigorous testing. This included all facets of the application and all supporting system resources, including, but not limited to, infrastructure, network, database, servers, and load balancers. Such a test would help all involved parties to discover exactly where the bottlenecks were and address them accordingly.
